Hypothesis
The study aimed to characterize thermophilic bacteria from Tao Dam hot spring that possess pectate lyase activity.
Conclusion
A. pallidus strain TD1 is a promising candidate for industrial applications due to its ability to produce extracellular pectate lyase.
Supporting Evidence
- Strain TD1 was isolated from Tao Dam hot spring and is capable of producing extracellular pectate lyase.
- The strain showed 99% identity to Aeribacillus pallidus DSM 3670T based on 16S rDNA analysis.
- Strain TD1 can grow at temperatures between 30–67 °C, with optimal growth at 55–60 °C.
Takeaway
Scientists found a special type of bacteria in a hot spring that can help make things like fruit juice clearer by breaking down pectin.
Methodology
The study involved isolating bacterial strains, performing microscopic observations, and conducting phenotypic, chemotaxonomic, phylogenetic, and molecular systematic analyses.
